(The College of Surgeons of Sri Lanka, 2011) Pinto, M. D. P.; Fernando, R.; Pathmeswaran, A.; Premathilake, M.; Fernando, T.; Edirisinghe, D.; Bandara, D.; Athulugama, N.; Abeysinghe, S.
OBJECTIVE: To assess the relationship between dietary goitrogens and the prevalence of goiter. METHODS:A descriptive cross-sectional study on the prevalence of goitre was conducted involving all areas of the country, except North and Batticaloa district from December 2006 to June 2007. A pre-tested interviewer administered questionnaire was used on all participants as a screening tool. Consumption of 6 possible dietary goitrogens was assessed. Sufficient frequency of consumption was taken as consumption >3 times a week. Pearson's chi-square test was used to analyze the significance of dietary goitrogens to the prevalence of goiter. RESULTS: 5200 participants were assessed (n=5200) island wide and 426 were detected with goitre. Mean age for occurrence of goitre was 36.3(+_17.3) years. Frequency of consumption of these food items was low, none being higher than 10% among the 5200 participants. Consumption of each goitrogen was as follows; Cabbage "[2.9%], Lima beans [9.9%], Kurakkan (Millet) [4%], Turnip [2.9%], Manioc(Cassava) [2.2%] and Peanuts [5.5%]. All six dietary goitrogens showed no significant association with the occurrence of goitre (p<0 05).CONCLUSION:Dietary goitrogens do not appear to have an association with prevalence of goitre in this cohort. As this cohort is a representative sample, dietary goitrogens are unlikely to be associated with prevalence of goitre in Sri Lanka.
Epidemiology of goitres in Sri Lanka - results of a community based study
(Sri Lanka Medical Association, 2008) Fernando, R.; Pathmeswaran, A.; Edirisinghe, D.; Abeysinghe, S.; Atulugama, N.; Bandara, D.; Premathileke, M.
BACKGROUND: lodization of salt was made mandatory in Sri Lanka in 1995. Data on the current prevalence and geographic distribution of goitre among the general population is not available. Objectives: To describe the epidemiology of goitre in the population over the age of 10 years in Sri Lanka DESIGN, SETTING AND METHODS: The country (excluding the Northern Province) was divided into 6 ecological zones based on annual rainfall and altitude. From each zone, 18 Grama Niladhari (GN) areas were selected, using the probability proportionate to size (PPS) technique. First household to be sampled was selected at random from the list maintained by the midwife and all eligible people in the house were sampled. The closest household, next to the index household,, was visited and sampling carried out next. The process was repeated until 50 subjects were sampled in a GN area. Each subject was examined by at least two researchers for the presence of a goitre. RESULTS: Total of 5200 subjects were assessed. 66 %( 3,433) were females. Mean (SD) age 36.3(17.3) years. 425 subjects had a goitre. The distribution of goitres according to the WHO categorization - Grades 1, 2, 3 and 4 was 18.6, 68.0, 12.5 and 0.9 percent respectively. Adjusted (age and zone) prevalence among females and males was 11.2% and 2.3% respectively. Adjusted (age and sex) prevalence (95% CI) in the different zones varied between 5.34% in the intermediate zone-south to 7.93% in the wet zone-hills. Overall adjusted prevalence was 6.8% (6.0-7.6). CONCLUSIONS: The prevalence of goitres is 6.8%. There is definite female preponderance. No obvious goitre belt can be discerned.
FNAC in the 'field'- a new experience
(Sri Lanka Medical Association, 2008) Fernando, R.; Hewavisenthi, J.; Pathmeswaran, A.; Edirisinghe, D.; Abeysinghe, S.; Atulugama, N.; Bandara, D.; Premathileke, M.
BACKGROUND: Fine needle aspiration cytology (FNAC) is an important diagnostic test in thyroid diseases. It usually is undertaken at a hospital or laboratory setup. As part of an islandwide field based study, FNAC was undertaken in the field. Literature review revealed that FNAC accuracy rate was around 65-70% in most Centres with full-fledged facilities. OBJECTIVES: To determine the effectiveness of FNAC done in the field DESIGN, SETTING AND METHODS: Informed written consent was obtained and the goitre was delineated with a marker pen. FNAC was carried out by a trained team member in the standard manner. Four slides were prepared from each patient. All slides were processed and examined by a cytologist RESULTS: 308 FNAC were done. 226 FNAC were diagnostic (73.36%) and 82(26.64%) were non diagnostic. 62(23.8%) showed benign cells only. The pathological entities detected were: 112 (49.5%) auto immune thyroiditis, 32 (14.1%) colloid storing nodules, 14(6.1%) colloid storing nodules with autoimmune thyroiditis, 5 (2.2%) follicular lesions and one toxic lesion. There were no significant complications noted in any of the patients. CONCLUSIONS: Field FNAC has a high diagnostic accuracy if done by a trained person. It is a safe procedure in the field.
The impact of access to finance on firm performance: evidence from microenterprises of sri lanka
(Faculty of Management Studies & Commerce, University of Jaffna, 2023) Liyanage, M.L.D.C.J.; Morais, S.N.,; Abeysinghe, S.; Wickramasinghe, C.N.
Lack of access to finance constantly emerges as one of the most imperative and robust underlying factors restricting firm growth and performance. Even though there were many literatures found on global scale there is very limited research conduct in Sri Lankan context, especially on the microenterprise’s perspective. Therefore, the main purpose of this study to fulfill this gap and investigate the role of access to finance on the performance of microenterprises in Sri Lanka. The study followed positivism philosophy and a deductive approach. As survey strategy was chosen, a structured questionnaire was used as the data collection tool from a sample of 385 Sri Lankan microentrepreneurs. The author has developed hypothesis and test them using the SPSS software. The findings indicate that increased access to finance has positive effects on the growth of profit, sales, and asset base of the micro enterprises. However, its impact of access to finance on employment generation was weak. Further, the study confirms the assumption that employment generation within microenterprise sector is persistently low. This study contributed to the local body of literature by analyzing the different employment groups of microenterprises and their relationship to access to finance in Sri Lankan context.
